New York, N.Y., a corporation of Delaware Filed Apr. 12, 1960, Ser. No. 21,805 Claims priority, application Netherlands Apr. 29, 1959 2 Claims. (Cl. 330-41) The invention relates to a dry shaving apparatus comprising a shear plate provided with apertures and a cutting member arranged behind this shear plate, while behind the shear plate and the cutter provision is made of a hair chamber to collect to the cut hair particles, the boundary walls of which chamber have one or more spring-actuated flaps through which the hair chamber can be emptied without the need for removing the shear plate and the cutter.

In accordance with the invention the flap is both rotatable and slidable and, in its closed position, it grips, on the side opposite the hinged suspension, behind its frame setting and is subjected to Spring pressure so that it is held behind the frame setting.

Thus the flap i locked in a simple manner and prevented from opening during operation of the apparatus. Moreover there is a possibility of utilizing the spring at the same time to hold the flap in the open position.

According to a further aspect of the invention only one spring is provided, which holds the fiap in its closed position behind the frame setting and which tends to turn the flap in the opened state, if the flap is shifted against the spring force.

The invention will be described more fully with reference to one embodiment.

FIG. 1 is a side elevation of a shaving apparatus constructed in accordance with the invention.

FIG. 2 is a sectional view taken on the line II-Il of FIG. 1 and FIG. 3 is an elevation of separate parts of the apparatus shown in FIGS. 1 and 2.

FIG. 4 is a front elevation view of the present shaving apparatus.

A dry shaving apparatus 1 is provided with two shear plates 2, behind which a hair chamber 3 is provided. Projecting through the hair chamber 3 is a drive shaft 14 supporting and connected to a cutting member 15. The walls 4 of this hair chamber include flaps 5, which can be opened to remove occasionally the cut hair from the hair chamber. The flaps 5 are secured to the housing of the apparatus only by means of one piece of spring wire 6. The ends 7 of the wire 6 are secured to the flap 5 and the center 8 is secured to the housing 9 of the apparatus. In the closed state the flap grips behind its frame setting 10. Due to the relative positions of the fastening places of the wire 6, this wire exerts a force on the flap 5 in an inward direction as shown in the drawing. The inwardly directed force exerted on the lower part of the flap 5 results in that the upper part tends to move outwardly. However, since the flap 5 grips behind the frame setting 10, an outward movement is prevented. However, if by mean of a ridge 11, the flap 5 is forced downwardly until it is disengaged from the frame setting 10, the flap pivots under the action of the spring. In the opened state lugs 12 fall behind depending flange 13, so that the flaps 5, in this position, are prevented from being withdrawn from the apparatus.

What is claimed is:

1. A dry shaver of the type provided with an apertured shear plate and a movable cutting member mounted under and adjacent thereto having a housing and comprising a frame mounting said shear plate, a chamber located under both said shear plate and cutting member for receiving cut particles of hair, said chamber being provided with at least one opening fiap which permits the cut hair to be emptied without removing the shear plate and cutting member, a spring connecting said opening flap to said chamber and exerting a force on said flap to retain the same in its open position, a catch on the frame of said shaver, one end of said flap being held in its closed position behind said catch on said frame by pressure of said spring, said flap having a ridge thereon whereby when force is exerted on said ridge in a downward direction said one end of the flap is disengaged from the catch on said frame and pivoted outwardly by pressure of said spring to thereby open said chamber, said spring having the ends thereof secured to said flap while an intermediate portion thereof is connected to said shaver housing.

2. A dry shaver as claimed in claim 1 further comprising a projection protruding from the bottom of the floor of the chamber and said spring being provided with a looped, intermediate portion, said looped portion being hooked around said projection.
